Implants for life Flashcards
What is the implant survival rate at 5 years
95%
What is the implant survival rate at 10 years
93%
What do we mean by Implant survival
The implant is there
What is try criteria for a successful implant
- Clinical immobility
- No evidence of peri-implant radiolucency
- Vertical bone loss of <0.2mm annually after the first year of service
- Lack of persistent irreversible symptoms
What is the success rate of single crowns cemented after 5 years
96.37%
What is the success rate of single crowns Screwed on after 5 years
91.16%
What is the success rate of fixed partial dentures cemented after 5 years
94.6%
What is the success rate of fixed partial dentures screwed on after 5 years
91.71%
What parts of the implant do we assess when identifying complications
- Prosthesis
- Abutment
- Perimplant tissue
If there is an issue with the prosthesis or abutment the complication is said to be
technical
If there is an issue with the peri implant tissue then the complication is said to be
Biological
What do we mean by peri implant tissues
hard and soft tissues
When an implant patient with removable prostheses comes in what do we look at
- Extensions
- Stability
- Occlusal wear
- Retention
- Abutment and insert
What problems can arise with fixed prosthesis
- Fracture or breakage
- Decementation
- Technical issues (more common in screwed prosthesis)
What are the problems with screw retained fixed prosthesis
- Loss of access crew hole restoration
- Loosening of abutment of prosthetic screws
- Wear\4. Chipping
Which restorations are more likely to be affected by biological complications
Cemented
Why are cemented prosthesis more Riley to be affected by biological complciaotns
Can be difficult to clear cement for the edges leading to biological interactions and complications
Give examples of biological complications affect peri implant tissues
- Peri implant mucositis
- Peri implantitis
- Plaque induced conditions
What is Peri implant mucositis
Reversible inflammatory reaction in the soft tissues
How many patients are affected by Peri implant mucositis
63.4%
What is Peri implantitis
Inflammatory reaction in the tissues surrounding an implant with loss of supporting bone
How many patients are affected by Peri implantitis
18.8%
How do you assess an implant
- visually
- Palpate it
- Is it mobile
- Smoker
- Oral hygiene
What do you examine visually when assessing a dental implant
- Colour
- Consistency; is there any swelling present
- Sinus
- Recession
What type of probe do we use to assess an implant
plastic probe
How much force should we use to assess an implant
25g around teeth
15g around implant
What are we looking for when probing around an implant
- 6 points
- Bleeding on probing
- Probing pocket depths
- Suppuration
Do we do BPEs around an implant
NO
What don’t we use BPEs around implants
Because the bone level is more variable around an implant
What does implant mobility indicate
Implant failure due to loss of osseointegration
How do assess the bone levels around an implant
Radiographic examination
Which radiographs can we take to assess bone levels
Panoramic
Periapical
When should we take radiographs to assess bone levels of an implant
2 yearly intervals
or
if any changes assessed
What habit can lead to increased failure risk of implant
Smoking
By how much can smoking increase implant failure
2.6 times
Smoking increases the risk of which bioligcla complication
Peri implantitis by 36.5%
How can periodontal history affect implant success
Rate of implant failure/ complications is higher in patient with a history of treated periodontal disease
What do we assess when looking at a patients dental history
Periodontal health
patietn attendance
When looking at etc implant restoration what do we look at
- Linked units
- Contour
- cement tupe
- Margin postion
How do we treat peri implant disease
Early and aggressively by:
- Giving OHI
- Non surgical debridement on a 6 or 3 month basis
- Modify the prosthesis ?
What can we use to carry out non surgical treatments of implants
Plastic carbon fibre enforced scalers are better as they are less likely to scratch the titanium
